Theoretical aspects of joint cultivation of vegetable and mushroom products indoors

Abstract

This article proposes a technology for simultaneous cultivation of mushroom, berry or vegetable products in a greenhouse consisting of two chambers – oxygen and carbon dioxide. The cultivation technology is based on the principle of plant responsiveness to aeration. During aerobic respiration, the amount of carbon dioxide released is approximately equal to the amount of oxygen absorbed, taking into account this pattern, a technology for cultivating the studied crops was proposed.

Introduction. Conducting joint research using sheltering greenhouses or tunnels, when cultivating fruit and mushroom products with mutual gas exchange, will lead to mutual and beneficial development of plants for further fruiting.

Object. Prefabricated greenhouses made with transparent or darkened halfpolypropylene. The greenhouse is divided into two equal halves by a partition for the separate cultivation of mushrooms and fruit and vegetable products, i.e. each crop has its own separate section.

Materials and methods. Soil racks are located in each half of the greenhouse, for the cultivation of products. In one half, a mushroom culture is cultivated, in the other, any other culture that absorbs carbon dioxide and releases oxygen during respiration, which will flow as a result of gas exchange through exhaust fans to the other half of the greenhouse. To monitor the level of carbon dioxide in the mushroom cultivation compartment, a carbon dioxide (CO2) detector is installed, with which the required level is maintained (up to 0.5%). The source of materials for growing mushrooms and vegetables are the theoretical and practical developments of scientists at VNIIOZ and VNIIGiM.

Results and conclusions. As a result of the development, the prefabricated greenhouse is equipped with a lowvolume irrigation system of the pipeline drip type with nozzles of fine sprinkling to maintain the necessary thresholds of soil moisture and air temperature. Two electric fans built into the partition from different sides and at different heights (in our case, greenhouses), will facilitate mutual gas exchange with timely activation, for the distillation of carbon dioxide and oxygen from one half of the greenhouse to the other, released during respiration by cultivated crops.
